摘要
采用微分进化算法应用于换热网络综合时,针对换热网络分级超结构模型中的整型变量即换热器有无问题,提出两种换热器协进化策略,分别利用差分进化原理与最小换热潜能约束实现换热单元协进化生成与消去,结合微分进化算法搜索合理的换热单元匹配。通过两个经典算例分析证明了算法的有效性,寻找到了更加符合实际生产的换热网络结构,优化结果较文献的年综合投资费用更低,用于工业生产过程中,可以稳定有效地节约成本。
The differential evolution algorithm was applied to heat exchanger network synthesis. Aimed at the existing integer variable problems in the super structure model,two strategies for the heat exchanger cooperation evolution were proposed,using the differential evolution principle and the minimal heat load constraint for the generation and elimination of the cooperation evolution of heat exchange units in order to find reasonable heat exchange unit matching by the combination of the differential evolution algorithm. The effectiveness of the algorithm was demonstrated through two classic examples and the heat exchanger networks in line with actual production were found. The total annual cost after the optimization was lower than those in literatures.
